How about on performance? Differentiating on a standard is not really following standard. That is to say, I'm not against it doing something crazy, like a replacement language for JS. Extraordinary efforts should bring equally extraordinary results.

I doubt these matter much to people outside the tech world. Everybody more or less now knows that Chrome is crazy fast. Also, I'm pretty sure the day Google decided to launch an entire OS based on this browser, everybody should have assumed that they wouldn't be that dogmatic about standards anymore.

That's conflating problems. Google doesn't need to add non-standard API to Chrome Browser so that Chrome OS can use non-standard API. They probably have branches.
